Hi there, A few days ago I asked about my evaporator freezing, wondering if it was the switch with the capillary tube that is inserted into it. I got some different suggestions so today I spent a little time with it. I checked the evaporator fins to make sure they were clear (they were for the most part but I cleaned them a little more), then ran the ac while right next to the evaporator. Almost instantly a bit of moisture formed on half of it. This continued to form until the moisture slowly began turning to ice. I could hear the switch right there cycling on and off but it is located in the half of the evaporator that was not icing. I took a quick drive and I could tell that the switch was cycling on and off when off things would begin to melt, when on they would freeze up again (freezing a little bit more area each time), all the while the section of the evaporator where the capillary tube goes in never even developed moisture. Any guesses? Oh, I also gave a quick visual inspection of the rest of the AC components while it was running, everything looked normal except for the receiver/drier site glass where the color was orange (is this my problem?). Thanks for your help John |
